Question

State two characteristics of solid catalyst

Answer 1

Characteristics of Catalysts are as follows:

1. The catalyst remains unchanged (in mass and chemical composition ) in the reaction (Activity of catalyst.)

2. A small quantity of the catalyst is required. e.g. One mole of colloid Pt catalyses 

3. The catalyst does not change the equilibrium constant. But the equilibrium approaches earlier

Answer 2

nickel is one of solid catalyst
it is used in changing the rate of reaction
it is not directly involved in reaxtion
